Jimjim - I agree for still air. The other 90% (or more!) of days would require a small forward (assuming straight vane!) component from the thrust vector.
To answer another facet of the question: On really strong wind days or when the landing surface (let’s call it a CVS) was moving into wind at a rate of knots - and therefore the wing was producing more lift than ‘normal’ - one still had to trim forward - so any moment requiring aft pitch (if there was one!) was overcome by the thrust vector needing to be angled forward to keep position.
And no, I’m not a trimmer.
